Hi All,
My 17025 audit just ended. Currently my laboratory provide onsite calibration for our customers who can't afford downtime on their equipment. Inside my SOP, it is stated that before bringing out the standard, engineer need to perform selftest/selfcal making sure the standard is working, redo the whole process at customer site and then finally when standard return from onsite. One of the auditor ask me whether by performing selftest/selfcal is good enough, how do I know the the calibration values will not be affected when the standard is transported to and fro. My questions are, is it necessary for me to re-validate my standard by performing re-calibration of my standard every time if I took the unit out? Can we sample check at some parameter points? Currently my standards were used for onsite probably 5-10 times in a year. Is there a method to do so?
A general question on clamp meter, how do we know the clamp meter used is a toroidal type or not? Most of the time there is no indication on the datasheet. I wanted to apply for accreditation for this and when i read on the specs for current coil that I am using, it specified 2 separate specification, one is for toroidal-type clamp meter and the other is any other type.
for the help.
